- Abstract
The aim of this study was to synthesize nano-hydroxyapatite-silica (nano-HA-Si) particles, followed by the evaluation of fluoride ion releasing property and color stability of conventional glass ionomer cement (cGIC) with the addition of nanohydroxyapatite-silica. Nano-HA-Si was synthesized by one-pot sol-gel technique. Experimental nano-hydroxyapatite-silica added GIC (nano-HA-Si-GIC) was prepared by adding 10% by weight ratio of nano-HA-Si to cGIC powder using manual mixing. Color measurements were measured according to Commission Internationale de l'Eclairage (CIE) L*a*b* system. Fluoride ion release was measured by fluoride ion selective electrode method. The 10% nano-HA-Si-GIC samples were successfully fabricated. Nano-HA-Si-GIC reported "slight - noticeable" change in color as compared to cGIC that displayed "noticeable to appreciable". Additionally, a highly significant increase in fluoride ion release was observed for nano-HA-Si-GIC samples as compared to cGIC (p=0.05). Incorporation of nano-HA-Si into the formulation of cGIC enhances the physical properties of the glass ionomer cement and provides a better-sustained fluoride release. Nano-HA-Si-GIC has the ability to enhance the characteristics of glass ionomer dental restorative materials. Hence, it can be suggested as a potential future restorative material in dentistry.
